Ricochet Robots
Alex Randolph’s board game Ricochet Robots offers a rich and versatile benchmark for ASP. As it stands, it represents a simple multi-agent planning problem in which each agent, i.e., robot, has limited sensing capacities (that is, only bumps are detected).
The Ricochet Robots visualization tool robotviz allows for displaying the board with barriers, robots, and targets as well as for animating robot moves in a stepwise fashion.
Note that the clingo examples (part of the releases) also contain an encoding and a visualizer for the ricochet robot problems.
